The stud member@ comprises a;

Steely.ritlinithe-.hel-leit bers areubrought together `the bo the shank 14 to the socket member. The neck ortion 17 of the stud will extend into the c amber l of the socket member and the head of the stud will likewise be contained within this chamber. When the stud and socket members are thus brought together a releasable retention of the members is obtained as follows Contained within the chamber l0 of the socket member is a set of spring arms 22, 23, respectively. These arms form the free ends of a spring wire 24. rlhis wire is bent along its middle to form an end piece from which the wire is further bent that its free ends ma provide the arms 22, 23 as aforesaid. T e wire 24 rests upon the plate 6 of the socket member and is Preferably held in place by a clip 26 cut from the body of the plate 6 and bent around the end piece 25 of the wire, thereby securely holding it in place. When the wire is thus secured the arms 22, 23 will extend substantially parallel with one another over the opening in the plate 6, the arms being normally separated from one another a distance less than the width of the head to the stud member and about equal to the width or diameter of the neck portion thereof. lVhen the stud member is applied to the socket member the rounding head of the stud will engage these arms and spread the` same, the arms slipping from off the head to engage the neck portion of the stud and lie beneath the edge 2l of the head. When thus disposed the arms will prevent separation of the stud from the socket member until such time as the arms are spread suiiiciently to permit the withdrawal of the head to the stud.

For the purpose of spreading the arms 22, 23 to release the head and permit of the withdrawal of the stud, there is provided a member 27 this member normally assisting, also, in the retention of the wire 24 and arms carried by it as will later be explained.

The member 27 is a member preferably struck up from a blank and comprises a hollow crown portion 28 from which extends a flange-forming edge or rim 29 provided at its opposite ends with downturned wedgeshaped projections 30. When in place the crown-forming portion 28 of the member 27 lies within and extends upwardly through the opening 8 in the plate 5 of the socket member. The crown rises so far above the face of the plate 5 as to permit of the depression of the member through application of pressure by the thumb or finger, the crown thus forming a thumb piece. The rim 29 extends in the mannerl of a flange outwardly beneath the plate 5 around the opening in it, thereb preventing withdrawal of the member 2 The wedge-shaped projections 30 fit downwardly Between the spring arms .,22, 23, the projections engaging the arms at points so far separatedfrom one another as not to interfere with the insertion of the head of the stud between the arms as previously described. The form and arrangement of the projections and their disposition in relation to the arms are also such that in th@l undepressed position of the member the edge or rim 29 will be held in engagement with the inner face of the plate 5 around the opening in it while the projections 30 will assist in holding the wire 24 and arms 22, 23 formed by it snugly in place against the face of the plate 6 and will prevent the arms and wire being lifted upon the insertion of the stud.

After the members have been brought together the head of the stud is released from the arms through an application of pressure by the thumb or finger to the crown portion or thumb piece 28 of the member 27, this action operating to depress the member when the wedge-shaped projections 30 thereof will operate to separate the arms 22, 23 sumciently to permit ofthe release and withdrawal of the head to the stud member. After the withdrawal of the head to the stud member and release of pressure from the member 27 the arms will resume their normal position and thereby act to elevate the member 27 and return it to the normal position occupied by it as above explained.

In further relation to the depressible meinber 27, it will be observed that its crown portion 28 ts rather snugly within the opening in the top of the casing and thereby assists in the positioning of the entire member, the lit of the crown in the opening permitting, however, of movement therein as aforesaid inasmuch as the wedge shaped projections 30 lit normally between the separable arms 22, 23. These arms accordingly, through engagement with the wedge-shaped projections, prevent rotary displacement of the member 27. To permit of the unobstructed movement of the projections 27 downwardly between the arms 22, 23, when the member 27 is depressed, the plate 6 of the socket member is provided with openings in it 31 located beneath the projections 30, one of these openings being the opening left from the bending up of the metal for forming the clip 26 above referred to.

Having thus fully described my invention, l claim and desire to secure by Letters Patent of the United States l. In a fastener, a stud member having an attaching head, a socket member having a casing with aligned openings in the top and bottom thereof, a resilient jaw within the casing for receiving and vholding the head of the stud member introduced into the casing through the opening in the bottom thereof on combining said members, and a depressible member having a hollow crown forming a thumbpiece extending through the opening in the top of the casing and depressible from outside the casing, said depressible member having also a flange interposed bewhen said depressible member is depressed by application of pressure to the thumbpiece.

2. In a fastener, a stud member having an attaching head, a socket member having a casing with aligned openings in the top and bottom thereof, a resilient jaw within the casing for receiving and holding the head of the stud member introduced into the casing through the opening in the bottom thereof on combining said members, and a depressible member having a hollow crown forming a thumbpiece extending through the opening in the top oit the casing and depressible from outside the casing, said depressible member having also a flange interposed between the jaw and the top of the casing adjacent the opening in it and parts extending from said flange to engage said jaw on opposite sides of the head of the stud member when the members are combined and operating to open said jaw for releasing the head of the stud when said depressible member is depressed vmember is depressed by by application of pressure to the thumbpiece. v 3. In a fastener, a stud member having a attaching head, a socket member having a casing with aligned openings in the topr and bottom thereof, means within the casing comprising spring arms arranged to receive and hold the head of the stud member introduced into the casing through the Opening in the bottom thereof on combining said members, and a depressible member having a hollow crown forming a thumbpiece eX- tending through the opening in the top of the casing and depressible from outside the casing, said depressible member' having a flange extending from said thumbplece and locatedinside the casing between the spring varms and the top vof the casing adjacent the opening therein and separate wedge-forming parts extending from said iangeonl opposite sides of the. head of the studgmemv ber when the members are combined, and operating to spreadsaid arms for releasing the head of the stud when-said depressible f application of pressure to the thumbpiece.
